In this report, we present a case of NKH-induced HC-HB exhibiting distinctive morphological and functional alterations on conventional magnetic resonance imaging (MRI), diffusion-weighted imaging (DWI), and 1H magnetic resonance spectroscopy (MRS), followed by subsequent monitoring. A 70-year-old male with a 20-year history of diabetes presented with severe unilateral involuntary movement. Computer tomography revealed heightened attenuation in the left putamen and caudate nucleus. The conventional MRI revealed the presence of focal T2-hyperintensity, noticeable mass effect, and ring-like enhancement, which are indicative of glioma. Additionally, the DWI showed unrestricted diffusion of water molecules within the lesion. MRS analysis further demonstrated significantly elevated lactate (Lac) and lipids (Lip), minimal increased choline (Cho), basically stable creatine (Cr), and modest decreased N-acetylaspartate (NAA) levels (which remained larger than both Cho and Cr peaks), leading to a diagnosis of NKH-induced HC-HB. This report emphasizes the significance of acknowledging that NKH-induced HC-HB can manifest with imaging features that bear resemblance to those of glioma. The presence of a slightly elevated Cho/NAA ratio alongside a notable increase in Lac/Lip peak on MRS may aid in ruling out neoplastic conditions.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"10 6","pages":"uaae043"},"PeriodicalIF":0.5,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11630835/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The procedure was initially successful; however, the patient developed ileus >1 month later and subsequently underwent several surgeries to treat the multiple metachronous ileal stenoses. The flux of a small amount of off-target glue was the primary cause of these complications. As the patient had few symptoms in the first month post-TAE, however, affirming the diagnosis took time. A detailed review of plain CT scans was a decisive factor in achieving the final diagnosis. This case demonstrates that TAE using an NBCA-iodized oil mixture effectively treats acute GI bleeding. However, a complication such as off-target embolization is likelier to occur because of a combination of certain factors such as vascular anatomy, complexity of the procedure, and NBCA dilution. Close observation using plain CT should be performed for the identification of off-target embolization occurrence even in cases of successful TAE.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"10 6","pages":"uaae042"},"PeriodicalIF":0.5,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11552622/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142628842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the setting of biochemical recurrence of prostate cancer, a suspected PSMA-avid (prostate-specific membrane antigen) lesion in the brain is still strongly suggestive of an intracranial metastasis of prostate cancer. This needs, however, a thoroughly recurrency work-up due to other potentially PSMA-avid cranial lesions, as PSMA initially was developed for the imaging of primary CNS tumours. We report of a challenging clinical case of a 71-year-old-patient with a strongly PSMA-avid lesion at the skull base. Given the medical history of a meningioma at the skull base, the further diagnostic work-up with MRI could still not rule out a malignancy, so that the patient needed to undergo a surgical excision of the tumour mass. The histological and immunohistochemical examinations revealed a relapsed CNS WHO grade 1 meningioma. From the aspect of molecular imaging and critical analysis of regular clinical care in a third-level university hospital, we consider this result very intriguing. Hence, we analyse the decision-making process and clinical course of this case in the light of molecular imaging findings.","PeriodicalId":45216,"journal":{"name":"BJR Case Reports","volume":"10 6","pages":"uaae041"},"PeriodicalIF":0.5,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11568342/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142649266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiograph of the neonate suggested malpositioned endotracheal tube. The fluoroscopic dye-study indicated gastroesophageal oesophageal reflux disease and nothing significant. On limited CT contrast study of thorax, a tubular structure was seen running just parallel to the oesophagus extending from the T2 to the T9 levels. Possibilities of a oesophageal duplication/IED were considered. The neonate underwent an endoscopy and gastrostomy on day of life (DOL) 9. On follow up at 3 months a repeat limited CT study was done with instillation of water-soluble contrast. The previously seen tubular structure running parallel to the oesophagus was no longer seen. This finding suggested a healed IED.

Not only it minimizes surgical trauma to patients, but also provide timely and accurate diagnosis for physicians to offer prompt appropriate treatment and avoid devastating outcomes. Tuen Mun Hospital, the neuroscience centre serving more than 1.3 million population in New Territories, Hong Kong, has been the pioneer in optimizing this novel modality within the district.
